HTML in comboxbox using xpages

I have a request to have the pull down values use a heading/indent style to combine like values together.

For example

Heading Name 1

Value 1

Value 2

Heading Name 2

Value 3

Value 4

I started with something basic just having a space before the value. This requires using

“&#160” in the pull down instead of the space.

<xp:selectItem itemLabel=“&#160;Value 1”></xp:selectItem>

Is there a way to do this.

I’ve tried <xp:comboBox escape=“true”> but this is not allowed.

I’ve also tried

						<xp:selectItems>

<xp:this.value escape="true"><![CDATA[${javascript:" Test"}]]></xp:this.value>

</xp:selectItems>

which will save in designer but has no affect on the output.

Any ideas for a solution to this?

Thanks in advance for any help or advice.
